Numerical Simulation of Persistent Slip Band Formation
During the transformation of the vein structure into the persistent slip hand structure in a copper crystal under fatigue (i.e. cyclic stress) the dislocation distribution undergoes complex microscopic changes. A roughly homogeneous distribution is converted into a periodic roll structure of many hundreds of wavelengths that crosses the crystal through its whole cross section.
